The impact of full and partial social cleavages on party systems: A comparative analysis of the countries of the former SFRY

Abstract

Party systems represent parts of political systems which arise as a result of interactions between political parties. Party relations produce characteristics which place a particular party system within the typology of party systems. A number of factors can be considered in explaining the nature of party competition, most often placed within the categories of institutional and sociostructural factors. This paper analyses the impact of full and partial social cleavages on party systems. Given that the theory of social cleavages has proved insufficient in explaining party differences and the dynamics of party systems, especially in new democracies, we will improve the analysis by including the concept of partial social cleavages. This research shows the unequivocal influence of dominant social cleavages on the situation and changes in party systems. Although in some cases no changes in the type of party system have occurred, it can be concluded that exactly in those cases there exist permanent and ingrained social cleavages, but also partial cleavages which affect the relations in the party system at the given time. Identity issues stand out as the dominant topic in political competition, especially in the countries where ethnic relations have not been resolved.
